As Emacs treesitter support matures, I've been adopting more and more of the built-in converted modes, for example
python-ts-mode in place of
python-mode, etc. There's a great article at
masteringemacs.org on the process, but essentially you can specify that when
python-mode would have been invoked, you should instead use
This is not copmletely transparent; in particular, hooks defined for the old
python-mode don't automatically run for
python-ts-mode as well.
The other day I found another omission, albeit with a fairly unobtrusive workaround. I use the yasnippet package for snippets1, and mostly rely on the yasnippet-snippets predefined collection. These are grouped by modes, and… not surprisingly a snippet defined in
python-mode does not automatically become available in
However — this examples assumes that you also load
~/.emacs.d/snippets/ — if you add a file
~/.emacs.d/snippets/python-ts-mode/.yas-parents, containing the single line "
python-mode", then all snippets defined in
python-mode will also be loaded and available in
